Question

Which of the following can transform matter from one state to another?

• A. Change in temperature
• B. Change in concentration
• C. Change in pressure
• D. Change in heat

Answer 1

Answer: (A), (C), (D)

The correct options are
A

Change in temperature

C

Change in pressure

D

Change in heat

Particles in solids have lesser kinetic energy when compared to liquids and gases. As temperature increases, the state changes from solids to liquids and then to gases. As amount of heat supplied increases, temperature increases and the state changes from solids to liquids and then to gases.
As the pressure increases, the volume of the container decreases. As we know, in solids, particles are much closer to each other and the distance between the particles increases as we move towards the gaseous state. So, with the increase in pressure, gases can be converted to liquids and then to solids.
